The movement protein (NSm) gene of Groundnut bud necrosis virus (GBNV) isolates from pea, mungbean, cowpea, French bean, tomato and potato collected from different locations of India were compared to study their diversity. The NSm gene sequences of all the GBNV isolates were highly conserved and had only 0–3% diversity in amino acids and 0–10% in nucleotides. Comparison of amino acid sequence of NSm gene of 25 GBNV isolates revealed the presence of many conserved regions. Both ‘Dâmotif’ and ‘Gâresidue’, the conserved regions of ‘30K superfamily’ of virus movement protein, were present in all the isolates. Clustering of the GBNV isolates does not appear to be based on their place of origin and host plant species.
